Traditional Sector antennas radiate very wide but very flat beam, with plenty of unwanted side lobes, that even change with frequency. Such beam performance is source to low noise immunity, co-location interference and null fill issues.

Symmetrical Sectors are low loss scalar horn antennas with unique beam shape and characteristics. Their beam section is circular: azimuth and elevation radiation angles are identical. The beam pattern does not vary with frequency and antenna gain is balanced over a wide frequency range. These features make them excellent for use as Sector antennas.
